BOTTLE-STOPPER.

Specification of Letters Patent.

Application filed October 5, 1911.

Patented Feb. 4, 1913.

Serial No. 652,952.

To all whom it may concern:

Be it known that I, CHARLES H. EDER, a citizen of the United States, residing at Chicago, in the countyof Cook and State of Illinois, have invented new and useful Improvements in Bottle-Stoppers, of which the following is a. specification, reference being had to the accompanying drawings, forming a part thereof.

The purpose of this invention is to provide an improved form of stopper or cap, adapted for use in connection with bottles, collapsible tubes and the like.

It consists of the features and elements described and shown in the drawings as indicated in the claims.

' In the drawings: Figure 1 is a side elevation of a collapsible tube fitted with a cap embodying this invention. Fig.2 is an elevation of the same partly in section, as indicated at the line, 2-2, on Fig. 1. Fig. 3 is a sectional view showing the cap in open position. Fig. 4 is a top plan view of the tube with cap in closed posit-ion, but not rotated to locked position. Fig. 5 is a top plan view of the tube with cap in closed and locked position.

The stopper, or cap, which is the subject of this invention, while readily adapt-able to serve for the closure of bottles or other receptacles. is shown as applied to the usual form of collapsible tube having a body, 1, made of soft metal which may be compressed to effect the discharge of its contents through the aperture, or throat, 2, of, the neck, 3. This neck, 3, is preferably constructed of material somewhat tougher and thicker than that of the body, 1, such that recesses, 3 may be formed in it to serve as pivot journals for the bent ends of the wire loop, 4, by which the cap, 5, is held in position. The end of the neck, 3, is preferably rounded ofi at 3 so as to approximate in form a segment of a sphere, and the cap, 5, is made spherically concave with about the same curvature at its under side. Thus a reasonable amount of pressure applied to hold the cap against the spherical end of the neck, 3, will serve to effect perfect closure of the aperture, 2; and if the curvature of the cap be made slightly greater than that of the end of the neck,3, it will be even more certain to be properly seated against the rim of the a erture, 2. The desired pressure between t e cap, 5, and the spherical end of the neck, 3, is secured by forming in the top'surface of the cap a diametrical groove or valley, 5, and by so dimensioning the wire loop, 4, that when this valley stands in registration with the wire, as shown in Fig. 4, the cap, 5, will be only loosely held against the end of the neck, 3. Then by rotating the cap, 5, to the position shown in Fig. 5, so as to bring a thicker portion thereof against the wire loop, 4, the cap may be securely bound upon the rounded end of the neck,'3, and the aperture, 2, will be effectively closed. The top surfaceof the cap, 5, is sloped upward to both sides of the valley, 5, with the same inclination so that rotation of the cap in either direction from the position illustrated in Fig. 4 will accomplish the desired closure of the aperture, 2, regardless of whether the operator be right-handed o'r left-handed. The cap, 5, is centered for rotation with respect to the wire loop, 4, by the lodgment of a bend, 4 in the loop in the recess, 5 formed in the uppersurface of the cap at its center.

For uncovering the mouth or aperture of the tube, it is only necessary to rotate the cap so as to bring its valley, 5*, into registration with the Wire, 4, as shown in Fig. 4; the pressure-between the cap and the tube being thus released, the cap may be readily swung to one side of the aperture, 2, about the pivotal ends of the loop, 4, to a position shown in Fig. 3. For insuring correct centering of the cap over the end of the tube when it is swung back for closure thereof, a pair of lugs, 3, are formed on the sides of the neck, 3, and provided with vertical grooves into which the lateral portions of the loop, 4, may be snapped as the loop assumes its vertical position.

1. In combination with a receptacle having a hollow body, and an apertured neck extending therefrom, the end of said neck being spherically rounded, a concave cap adapted to be seated upon the rounded end of said neck, a wire loop extending from the neck over the cap, the ca being of different thicknesses at its di erent axial sections and being adapted to be rotated about its axis for securement between the loop and the end of the neck, and the loop being pivotally secured to the neck for swinging across the end thereof.

2. n combination with a receptacle having a hollow body, and an apertured neck extendin therefrom, the end of said neck being sp ierically rounded, a concave cap' adapted to be seated upon therounded end of said neck, a wire loop extending from the .neck over the cap, the cap being of different thicknesses at its different axlal sections and being adapted to be rotated about its axis for securement between the loop and the end of the neck, the loop being pivotally secured to the neck for swlnging across the end thereof, and the cap being swivelly engaged by the loop.

3. In combination with a receptacle having a hollow body and an apertured neck extendin therefrom, the end of said neck being -sp erically rounded, a concave cap adapted for seating upon the rounded end of said neck, a wire loop extending from the neck over the cap, said cap being of different thicknesses at its different axial sections and being rotatable about its axis for securement between the loop and the end of the negi, the loop being pivotally secured to the eck for swinging across the end thereof, the outer face of the cap having a central depression, and the 100 being bent into said depression for swive ly engaging the cap.

4. In combination with a receptacle having a hollow body and an apertured neck extendin therefrom, the end of said neck being sp erically rounded, a concave ca adapted for seating upon the rounded en of said neck, a wire loop extending from the neck over the cap, said cap being of different thicknesses at its different axial sections.-

and being rotatable about its axis for securement between the loop and the end of the neck, the loop being pivotally secured to the neck for swinging across the end thereof, the outer face of the cap having a central depression, the 100 being bent into said depression for swive 1y engaging the cap, the receptacle having a shoulder at the base of the neck positioned to limit the swinging of the cap in the loo and the transverse thickness of the neck Being suflicient to prevent disengagement of the cap from the loop at such limit of swing.

5. In combination with a receptacle having a hollow bodyand an apertured neck extending therefrom, the end of said neck being spherically rounded, a concave cap adapted for seating upon the rounding end of said neck, a wire loop extending from the neck over the cap, said cap being of difi'erent thicknesses at its different axial sections and being swivelly engaged by the loop to permit rotation about its axisfor securement between said loop and the end of the neck, the loop being pivotally secured to the neck for swinging across the end thereof, and the dimensions of the neck being sufficient to prevent disengagement of the cap from the loop throughout such swinging movement.

In testimony whereof I have hereunto set my hand at Chicago, Illinois, this 2nd day of October, 1911.
